Spotted garden eels (scientific name Heteroconger hassi) secrete a mucous that they then use to coat and cement together the sands of their burrows!

Shortnose Greeneye (scientific name Chlorophthalmus agassizi) eyes fluoresce bright green in dim blue light!

Northern hogsucker (scientific name hypentelium nigricans) are good indicators of overall good water quality, as they are very susceptible and intolerant of water pollution and other water channel disturbances!

African lungfish (scientific name protopterus annectens) have a lung and are good at withstanding longer periods of drought, as they burrow in the mud and secrete a mucus around themselves that then hardens into an almost cocoon like structure! They can survive for up to a year this way, waiting for the waterways to fill up again.

Silver Spinyfins (scientific name dretmus argenteus) have 38 ospin genes for the rods in their retinas, so that they can see well in very low light! This is especially useful since they are deep sea fish!

Atlantic threadfin (scientific name Polydactylus octonemus) can have up to nine pectoral filaments (the long whiskery fins)!

Sockeye Salmon (scientific name oncorhynchus nerka) can use their sense of smell to find their home streams, as well as sense predators and chemicals in the water!
